摘要
碳纳米材料(碳纳米管和石墨烯)纤维具有优异的力学和电学性质,能够被应用在柔性可穿戴器件力学和储能器件等领域~[1-2]。然而目前报道的通过氧化还原法制备的石墨烯纤维片层表面含有大量的含氧官能团和结构缺陷,使其电学性能和机械性能不理想~[6-9]。石墨烯纤维在可穿戴储能器件领域的应用尤其是超级电容器方面的应用,不但要求材料具有高的导电性,同时要求具有优异的机械性能;我们采用化学气相沉积法制备石墨烯纤维具有完整的晶格结构、优异的电学和力学性能。进一步地通过控制反应条件在石墨烯层间定向生长垂直和平行石墨烯片层方向的碳纳米管(CNTs),提高纤维的机械性能和导电性。这种石墨烯/CNTs交联复合结构纤维用于超级电容器电极材料,具有优异的电化学表现。
Carbon material fibers including carbon nanotubes(CNTs) or graphene with excellent mechanical and electrical properties are highly in demand for modern microelectronics, especially applications in flexible and wearable devices. Recently reported graphene fibers are usually produced via soluble process of wet–spinning using insulating graphene oxide as starting precursor, followed numerous oxygen-containing functional group and defects, which substantially degrades the conductivity and mechanical properties. Graphene fiber with flexible and stretchable can be applied in flexible wearable storage devices, especially in supercapacitor. We fabricated graphene fiber with outstanding electrical and mechanical properties by chemical vapor deposition(CVD) grown on graphene bundles. In addition, graphene fiber with aligned carbon nanotube arrays can be prepared, which improve the conductivity, strength and stretchability. Furthermore, the performance of thus-prepared fiber-based supercapacitors was greatly improved.
